Bump!
Picked up the complete collection today, 6 movies plus 6 bonus discs, and had a chance to preview a couple of scenes. Started out with A Phantom Mennace, picture and sound are excellent. Previewed the pod race, demo material for sure.
Watched a little bit of A New Hope, not so impressed. I can remember when the 4-6 came out on DVD and was very impressed with picture, but I wasn't as wowed with the bluray like I was the dvd's. Again, just a few minutes of watching, so maybe the other movies look better.
